m ), thin, and horizontal. Location Mid and upper lung zones, radiating from the hila. Peripheral lung bases (costophrenic angles), touching the pleura. Anatomy Thickened septal plates between lung segments and subsegments. Thickened interlobular septa at the lung periphery. Prevalence Less frequent; usually seen only when B lines are also present. Most common finding in heart failure (HF) and pulmonary congestion. Pathophysiology and Significance Mechanism
Kerley A lines represent thickening of the . Because these septa contain lymphatic connections between the central (hilar) and peripheral areas of the lung, they appear as long, non-branching lines radiating outward from the center of the chest. kerley a vs b lines
Kerley lines are a crucial radiological finding in chest X-rays, particularly in the diagnosis of heart failure and other pulmonary conditions. These lines represent interstitial edema and are a key indicator of fluid overload in the lungs. There are two types of Kerley lines: Kerley A lines and Kerley B lines. Understanding the differences between them can help in making accurate diagnoses and guiding treatment. m ), thin, and horizontal
